Biddle was designated for assignment by the Pirates on Friday.
The move is to make room for David Freese on the 40-man roster and leaves Biddle's future in doubt for the second time this offseason. Biddle landed with the Pirates after getting designated for assignment by the Phillies. Whichever team he lands with will have to be patient if it thinks he can still be a major league pitcher, as he's out for the entirety of 2016 due to Tommy John surgery and had control issues before the injury.
